Reviewing 2020 Weedy Rice

The University of California Cooperative Extension has released a year-end review of weedy rice in the Sacramento Valley. 

Their findings include six confirmed cases through the 31 samples received and evaluated. They also completed a survey of all weedy-rice infested fields between 2016 and 2019. Of the 11,000 acres of inspected fields, just 2,300 acres were recorded as infested.
